Planet Neptune

Elements found on Neptune include:

Molecular hydrogen (H2) - 80.0%

Helium (He) - 19.0%

Methane (CH4) - 1.5%

Hydrogen Deuteride (HD) - 192ppm

Ethane (C2H6) - 1.5ppm

Ammonia ice

Water ice

Ammonia hydrosulfide

The circumference is about 155609 KM (equitorial).
96,685 miles (155,600 km).

To revolve once around the Sun takes Neptune almost 165 Earth years (164.79 years).
Because Neptune is not a solid body, its atmosphere undergoes differential rotation. The wide equatorial zone rotates with a period of about 18 hours, at the polar regions the rotation period is 12 hours. Its magnetic field rotates in 16H 6 MIN 36 SEC. Its orbit around the sun (Neptunian Year) is 60,190 earth days or about 164.79 earth years.

Earth and Venus are very similar in size. Earth's diameter is 12,742 kilometers and the diameter of Venus is 12,100 kilometers.

The Roman god of the sea is Neptune. He is the counterpart of the Greek god Poseidon and was often depicted carrying a trident. Neptune was also associated with horses and earthquakes.

According to Wikipedia, in Chinese, Japanese, and Korean, the planet's name was translated as "sea king star" (海王星). In Mongolian, Neptune is called Dalain Van (Далайн ван), reflecting its namesake god's role as the ruler of the sea. In modern Greek the planet is called Poseidon (Ποσειδώνας, Poseidonas), the Greek counterpart of Neptune. In Hebrew, "Rahab" (רהב), from a Biblical sea monster mentioned in the Book of Psalms, was selected in a vote managed by the Academy of the Hebrew Language in 2009 as the official name for the planet, even though the existing Latin term "Neptun" (נפטון) is commonly used. In Māori, the planet is called Tangaroa, named after the Māori god of the sea. In Nahuatl, the planet is called Tlāloccītlalli, named after the rain god Tlāloc.

The period of rotation (day) on Neptune varies by latitude, but the core rotation takes about 16.11 Earth hours. (16 hours, 6 minutes, 36 seconds) The atmospheric rotation appears faster near the poles (about 12 hours to rotate once) than at the equator (about 18.1 hours to make a complete rotation).

Neptune does not have the same type of solid surface found on Earth and the smaller planets. Under the thick hydrogen-helium atmosphere is a dense slush of water, ammonia, and methane, with only a small rocky Earth-sized core.

This question is quite difficult to answer, as the Earth and Neptune's orbits are constantly in progress at different speeds, and vastly different distances from the Sun, which changes the distance between the two objects.

The average distance between the Sun and Neptune is 4.46 billion miles (30.06 AU). The Earth is exactly 1 AU from the Sun, so if all three objects were in conjunction (aligned with each other), with the Sun at the end, Neptune would be approximately (29 AU) distant from Earth. If all three were in conjunction with the Sun in the middle, the distance between Earth and Neptune would be just over (31 AU).

We can say, then, that the distance between Earth and Neptune is between 29 and 31 AU, depending on their position relative to the Sun and each other.

Neptune has a fairly constant temperature of 72 degrees Kelvin. 200 c

Because Triton revolves around Neptune opposite its rotational direction it is considered retrograde. This indicates that it was likely a planetoid that was captured by Neptune's gravity rather than having formed in orbit around Neptune.

Neptune is a gas giant composed mostly of hydrogen and helium, so it doesn't have a solid surface like Earth. Its atmosphere is primarily made up of hydrogen, helium, and methane gas. There is no solid terrain to speak of on Neptune.

Neptune is a planet in our solar system and is not a character in a movie. However, there are movies that feature space exploration where Neptune may be mentioned or visited as part of the storyline.

Neptune was predicted by mathematical calculations and first observed on Sept 23, 1846 by Johann Galle, Urbain Le Verrier and John Couch Adams.

This was the first time Neptune was observed, as it is not visible with the naked eye.

No, Neptune doesn't have a solid surface for there to be volcanoes.

The 13 known moons are far fewer than the 60+ totals of Jupiter and Saturn, and most are likely not in their original forms. It is suspected that the one very large moon, Triton, was captured gravitationally and caused the complete disruption of the existing moon system. The current rings and moons contain substantial amounts of ice, and some may be fragments from collisions.

Neptune is the Roman god of water and the seas. His greek counterpart is Poseidon.

He rules everything that has to do with water: naval battles, fishing, sea monsters, etc. He has a powerful trident (just like Jupiter/Zeus has a thunderbolt).

Poseidon/Neptune also rules horses. The Greek legend says that he offered the horse to the Athenians, so that they would choose him as god-protector of their city.

It is a gas giant. It is mostly gas but is believed to have rock and ice core about 9500 miles in diameter. So there is a surface under a dense atmosphere over 10,000 miles thick of mostly hydrogen and helium with a small amount of methane. The temperature at the surface is -200 degrees Celsius. The planet has the highest winds of any planet in the solar system, reaching up to 1,200 mph. The surface pressure is 980 times that of Earth's.

Neptune takes 164.79 Earth years (60,190 Earth days) to orbit the sun.

In 1989, Voyager 2 flew by Neptune and photographed a Great Dark Spot about the size of Earth. Like the Great Red Spot on Jupiter, the Great Dark Spot was probably a giant storm. But the storm didn't last long. Images taken fice years later showed that the Great Dark Spot was gone.

Neptune is tilted on its axis because of the presence of other planets and gravitational forces within the solar system. These interactions can cause a planet to tilt over time, affecting its rotational axis. In Neptune's case, it has a significant tilt of about 28.3 degrees compared to Earth's 23.5-degree tilt.

The concept of getting dizzy is based on liquid that is somewhere inside your head near both of you ears. When you spin around and around, that liquid keeps swiahing around too. When you stop, the liquid is still spinning, so you still feel like your spinning. That's how you get dizzy. So yes obviously now you can get dizzy in space.

No, it is not possible for a human colony to survive on Neptune. Neptune is a gas giant with extreme weather conditions, including high winds, extremely cold temperatures, and a lack of solid ground. It also lacks a solid surface for structures or infrastructure to be built upon.

Neptune's circumference is approximately 155,600 miles (250,560 kilometers).
